Problems solved by technology

Among all kinds of motors in use in my country, more than 80% are small and medium-sized asynchronous motors below 0.55 to 200kw, of which JO2 series motors equivalent to the technical level of the world in the 1950s account for about 20%, which is equivalent to Y in the late 1970s. The proportion of high-efficiency motors of the YX series with the level of the 1980s is even negligible. Among the 250 million kilowatt-capacity motors driving fans, water pumps, and compressors in my country, more than 70% should be adjusted However, so far only about 20% of them operate with speed regulation, and most of them operate at a constant speed, which causes serious waste of electric energy, especially in small and medium-sized enterprises.
[0003] China is becoming one of the world's largest production bases for motors and motor system components, but the energy saving situation of motors in China is not optimistic

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0013] The present invention only needs to change the stamping die of the stator punching sheet, and the material of the stator punching sheet adopts the 50WW470 cold-rolled sheet currently promoted by the state. Use 50WW470 cold-rolled silicon steel sheet to punch out the stator stamping body 1 on a punching machine. On the circumference of the stator stamping body 1, buckle slots 3 are evenly distributed, and the buckle slots 3 are 6 slots. Stator punching slots 2 are uniformly arranged on the stator punching body 1, and the stator punching slots 2 are 36 slots. In the stator punching groove 2, the inner diameter of the punching piece is a=Φ103.8mm, the diameter of the groove bottom is b=Φ157mm, the diameter of the buckle groove is c=178, the outer diameter of the punching piece is d=Φ181mm, the slot width of the buckle piece is e=10mm, and the positioning M...

Abstract

The invention discloses a stator lamination for a high-efficiency servo motor, which comprises a stator lamination body. Stator lamination grooves are uniformly arranged on the stator lamination body. The stator lamination is characterized in that the inside diameter a of the lamination in the stator lamination groove is phi103.8 mm; the bottom diameter b of the groove is phi157 mm; the diameter c of a lamination buckling groove is 178 mm; the outside diameter d of the lamination is phi181 mm; the opening width e of the lamination buckling groove is 10 mm; the semi-diameter f of a location mark is R1 mm; the angle g of the lamination buckling groove is 30 DEG; the angle h of the location mark is 10 DEG; the angle K of the lamination buckling groove is 60 DEG; 36 stator lamination grooves are arranged; the lamination buckling grooves are uniformly arranged on the circumference of the stator lamination body; and six lamination buckling grooves are arranged. According to the stator lamination for the servo motor disclosed by the invention, the efficiency of a motor can be greatly increased; the electromagnetic noise of the motor can be reduced when the motor is in the operation process; therefore, the motor is low in starting current and high in starting torque; furthermore, a stamping die of the stator lamination is only necessary to be changed; and the original assembly mode of the motor is not changed.

Description

technical field [0001] The invention relates to a stator stamping sheet for a servo motor, in particular to a stator iron core with 8 poles in the servo motor. Background technique [0002] In today's society where global resources are scarce, people's awareness of energy conservation and emission reduction and low-carbon life is increasing day by day. Our country is also vigorously promoting energy conservation and emission reduction, and improving the energy efficiency of electric motors is one of the ways to achieve this goal. one. The motor is an indispensable driving device for the production and operation of industrial and mining enterprises. The total installed capacity of motors in my country has reached more than 500 million kilowatts, and the annual power consumption is 800-1 trillion kwh, accounting for about 60% of the country's total power consumption. , accounting for about 75% of industrial electricity consumption. Among all kinds of motors in use in my coun...
